Box loom



Aug- 23, 1932. I. MERCIER Y soLE BOX LOOM Filed Dc. 20. 1929 Patented Aug. 23, 1932 UNITED STATES ISIDRO MERCIER Y soLE, or BARcELoNmsrAm BOX LOOM Application filed December 20, 1929, Serial In box looms designed for weaving with 710 ment has been considerable this interferes the rear wall of the shuttle box, protruding 35' to its own elasticity, leaves the shuttle completely free when the box is brought into the working position and, on the contrary, when the box is not working the spring or retaining piece bears against the shuttle over the greater length of the same so preventing its displacement.

For the purpose of the mechanism, each of these springs has an arm that passes through from the same, and in combination with this arm a guide plate is fixed to the upright of the batten, this latter having such a form as to press all the arms of all theboxes with the exception of that which is in the working position.

In the attached plan all the parts of a box loom are shown, to which the improvement, the object of this patent, has been applied.

Figure 1 is a view seen from above of one end of the batten, the loom boxes being shown partially in section as indicated by the line I-I of Figure 2. Figure 2 is a vertical sec tion taken through the line II-II'of Figure 1. Figure 3 is a detail of the boxes seen from above. Figure 4 is a View in perspec- No. 415,586, and inspain March 1, 1929..

tive, in small scale, of the retaining spring of the shuttle, The loom is generally composed of a bat ten l with its Verticals 2 and a set of boxes '3 that slide on the guides 4 moved by a convenient mechanism. These boxes have the usual device in looms'a'ndj each of them is provided, as is also usual,- With the corresponding box swell;

This improvement, constituting the object of thisapplication, consistsin applyingto each of the boxes a retaining device which in the example represented in the figures is composed of 'a long spring -6 which occupies nearly the entirelength ofthe shuttle box.

' These springs are strips of steel designed with a longitudinal'aperture 16- in order to allow the 'entranceof the box swell 5" and they have one extreme bent forming an arm- 7 that passes-through an orifice made in'the rear wall of the shuttle box coming out at the rear part of the box.

' In combination with these springs .-67,+' a support 9+ is provided fixedtothe vertical ''2- of the batten, which supports a guide plate 10' which presses the arms -7-'. Aswill be seen' inv, Figure 2, this} piece".-'l0- forms a vertical plane butit has an angular recess}f1 1 in the part op: posi'te to the shuttle box 30 when the latter is in the .workingposition so that the. spring -6 ofthe-box 30 presses, by its own elasticity, against the rear wallof the box and for this'reason does not in.th'eleast hinder thein and out movement of the shut tle, While onthe contrary, in the case of the other boxesof the mechanism the arm 7- is pushed by" the guide plate .10 and the spring 6 is introducedinto the interior of the shuttle box, takingthe form shown in. the plan, pressing against the shuttle .8+ as is shown in Figure 1."

Due to the elf ctof the pressure of the spring 6 against the shuttle 8-, the

latter becomes absolutely fixedrin the interior of .thebox not being ableto fget displacedby the vibration and movementsjto which it is" subjected duringthe'working of theloom i p 'Iheguide plate -'-10? acts'durin'g the nor; mal working of the 100m as a'fixed piece, but

it is convenient that the support 9 that holds it should be in the form shown in-the plan or such other form as should be convenient to allow a certain elasticity in order to avoid breakdowns should the working of the boxes cease to be normal.

In order to avoid the vibration of the swell boxes, in the mechanism of this application, there has been applied to the upper part of V the set of shuttle boxes 3- an arm"'1'2' which is curved" as is indicated in F-ig ure g and which has a vertical arm '13 pointing downwards to come into contact with theex treme end of the box swells 5, the space between the two parts-beingirelatively short, so that the oscillating of the box swells that are.

' not workingis limited by this vertical, arm

-13 the. box swells being in this manner prevented fromhindering the working of the mechanism. Y

I As will be imderstood, it is not absolutely necessary that thereta'ining device be c0nsti-- tuted 'bya spring of exactly the form shown V in the drawing", but, on the other hand, its "form" can be'v'aried always provided that it be an oscillating part which, byits elasticity,

can permitthefreemovement of the shuttle,

comes into position against the shuttle the same in the interior of the box;
